db\ActiveRecord insert()

Inserts a row into the associated database table using the attribute values of this record.

This method performs the following steps in order:

1. call beforeValidate() when $runValidation is true. If beforeValidate() returns false, the rest of the steps will be skipped;
2. call afterValidate() when $runValidation is true. If validation failed, the rest of the steps will be skipped;
3. call beforeSave(). If beforeSave() returns false, the rest of the steps will be skipped;
4. insert the record into database. If this fails, it will skip the rest of the steps;
5. call afterSave();

In the above step 1, 2, 3 and 5, events EVENT_BEFORE_VALIDATE, EVENT_AFTER_VALIDATE, EVENT_BEFORE_INSERT, and EVENT_AFTER_INSERT will be raised by the corresponding methods.

Only the changed attribute values will be inserted into database.

If the table's primary key is auto-incremental and is null during insertion, it will be populated with the actual value after insertion.

For example, to insert a customer record:

$customer = new Customer;
$customer->name = $name;
$customer->email = $email;
$customer->insert();
